老年桡骨远端干骺端粉碎性骨折患者可能需要植骨填充骨缺损。在这项回顾性、非随机、单一外科医生研究中，我们评价了使用两种背侧锁定接骨板联合或不联合矿化胶原（MC）植骨加固治疗桡骨背侧干骺端粉碎性骨折老年患者的临床和影像学结局。第1组（n= 12）采用背侧锁定钢板结合MC植骨治疗干骺端骨缺损，第2组（n= 12）仅采用背侧锁定钢板治疗干骺端骨缺损。在术后3个月和12个月测定临床和影像学参数。在最终随访时，两组之间在手掌倾斜和桡骨倾斜方面没有显著差异（p= 0.80）;然而，在第2组中，使用背侧锁定钢板治疗而没有加固的尺骨变异显著增加（p< 0.05）。在功能上，两组之间没有显著差异。我们的初步研究表明，MC作为骨移植替代物和背侧锁定钢板的组合可能是一个有用的替代老年患者干骺端粉碎性桡骨远端骨折。
Bone graft may be needed to fill bone defect in elderly patients with a metaphyseal comminuted distal radius fracture. In this retrospective, nonrandomized, single-surgeon study, we evaluated the clinical and radiologic outcomes of using both dorsal locking plates with or without augmentation with mineralized collagen (MC) bone graft for elderly patients with dorsally metaphyseal comminuted radius fractures. Patients in group 1 (n= 12) were treated with dorsal locking plates with MC bone graft application into the metaphyseal bone defect, and those in group 2 (n= 12) only with dorsal locking plates. Clinical and radiologic parameters were determined at three and 12 months after surgery. At final follow-up, no significant difference was noted between the 2 groups in terms of palmar tilt and radial inclination (p= 0.80); however, ulnar variance increased significantly in the group 2 treated with dorsal locking plates without augmentation (p< 0.05). Functionally, there was no significant difference between the groups. Our preliminary study suggests that combination of MC as bone-graft substitutes and dorsal locking plates may be a usefully alternative for elderly patients with metaphyseal comminuted distal radius fracture.
